dc.description.abstract	The study of the properties of inclusive production of D(s) mesons and of events in which a phi and a muon are present in the same jet provides two independent measurements of the probability, f(s)w, for a heavy quark to hadronize into a strange B or D meson. The data sample analysed corresponds to 243,000 hadronic Z0 decays. The combined value of these measurements is f(s)w=0.19+/-0.06+/-0.08. From the flight distance distributions of D(s) and of (phi-lepton) secondary vertices, with the lepton emitted at high transverse momentum relative to the jet axis, two values are obtained for the B(s)0 meson lifetime. Combining these measurements with a previous result based on the study of D(s)-mu events, the B(s)0 meson lifetime is measured to be: 0.96+/-0.37 ps.
